The grooves in this photo are currently filled with water forming elongate lakes. Sperry Glacier carved out these grooves when the
glacier was larger than it is today. The photo was taken where the camera is located on the topographic map. In this photo, you are
looking toward the northwest. Just past the end of the grooves you can see some sandy-looking hills or mounds in the photo. These are
part of an end moraine. Off in the distance, you see some mountain peaks in the photo. These peaks are off the section of topographic
map shown here. Sperry Glacier, which shows on the map, is out of the photo off to the lower right.
On the topographic map, north is toward the top of the map. Sperry Glacier is shown in white with blue contour lines and a dashed blue
line marks the border of the glacier. Some of the lakes in the photo appear on the map in blue. The grooves not containing water are shown
by the bends in the contour lines just beyond (northwest of) the edge of the glacier. In order to see the falls labeled on the map and
Avalanche Lake at the base of the falls, you would have to walk out to the end moraines, over the top of the moraines, and then you could
see the steep drop-off where the falls are located.
